Abstract
A system for simultaneously forming multiple flutes in a carbide rotary cutting tool includes a chuck adapted to grasp a green rod member and selectively rotate the green rod member about, and translate the green rod member along, a first axis. The system further includes a mechanism adapted to simultaneously machine multiple flutes in the green rod member as the green rod member is rotated about, and translated along, the first axis.
Claims6
A method for forming a rotary cutting tool, the method comprising:
- securing a green rod member which has been previously formed in a generally cylindrical shape in a chuck mechanism, the chuck mechanism being adapted to rotate about, and translate along, a first axis in a predetermined manner;
- simultaneously forming a plurality of flutes in the green rod member by machining;
- removing the green rod member from the chuck mechanism;
- sintering the green rod member to produce a sintered rod member;
- and
- performing one or more grinding operations on the sintered rod member to produce a finished rotary cutting tool.
